The present invention relates to foldable containers and more particularly, to an improved box or receptacle that may be formed from a blank at a minimum expenditure of time and labor.

An important feature of the invention is to provide a strong and durable box that is formed from a blank and which is so constructed as to be capable of withstanding the exacting usage to which articles of this kind are subjected.-

A further object consists in providing novel means: for .maintaining the bottom, sides and top of a knockdown box in proper position when the box is assembled.

Other objects and advantages of the invention will become apparent from the following description when taken in conjunction with the accompanying claims and drawings.

Referring to the drawings in which are shown several embodiments the invention may assume:

Figure 24 is a perspective view of the assembled blank shown in Figure 23;

Figure 25 is a plan view of another modification;

Figure 26 is a perspective view of a box formed from the blank shown in Figure 25.

Referring to the drawings in which like nupair of projections l2 and I4 having extending therefrom, the similarly formed portions l8 and 19 that constitute the top of the box and are provided with medially disposed looped handles 20 arranged to be bent along the score lines 2| so as to extend upwardly from the top in adjacent relation, to assume the position shown in Figure 2. The top sections l8 and i9 are also provided with the marginal flaps 22 having tabs 23 which, when the box is assembled, are bent downwardly over the top so that the interlocking portions of the tabs will fit within adjacent pairs of slots 24 formed in the sides l3 and I4 respectively; each pair of slots 24 has spaced inclined openings terminating in inwardly extending end portion 24'. The sides l3 and I5 within the slots 24 may have the creasing orv score lines 23' which constitute hinges for facilitating the introduction of the tabs into the slots 24. The opposed ends of the top sections l8 and I9, when the box is assembled are formed with intermediate flaps 25 which overlap so'that one will extend through the openings in the handles 20 and the other will engage the under surface of the top flap. The top sections are also provided with end flaps 26 which extend in overlapping relation to each other beyond the base of the handles '20.

In the modification shown in Figure 3, the intermediate portion 21 of the blank is of substantially the same shape as previously described, and the blank is provided with the score lines 28 so as to form the sides 29 and the top sections 30 when the box is assembled. The flaps 3| formed on the top sections 30 are provided with the tabs 32, each adjacent pair of which overlap to fit within the openings 33 in opposed sides 29 when the box is set up. 1

In Figure 4, the box is formed from the blank sections 36 are provided with tabs 31 having shoulders 38 arranged when the tabs are in-v 19 which fit Within the slots 19'.

34 which is similar to the form shown in Figure 1 with the exception that the flaps 35 on the top sorted in the spaced openings 39 in the opposed sides 40, to provide an interlocking connection for ure 5, the bottom M, the opposed pairs of sides 42 and 43, and top sections 44 are preferably embossed as at 45 so as to provide strengthening means for reinforcing the box. The opposed sides 43 have medially disposed slots 46 arranged to receive the tabs 41 on the flaps 48 that extend from the top sections 44 and are arranged to be bent downwardly over the sides'so as to assume the position as shown in Figure 6. The sides 43 may have the tabs 49 which, when the box is assembled, are arranged to fit within the openings 50 in the flaps 48 to provide additional fastening devices for maintaining the parts in position..

The handles, 5|, which extend upwardly from the top sections 44 and their associated parts are substantially similar in construction to the han-' dies previously described.

The form shown in Figure '7 is very much similar to the box shown in Figure 5 and essentially distinguishes therefrom in that the opposed sides 52 are each provided with spaced curved slits 53 arranged to receive the projections 54 on the tab 55 that extends from the flaps 56 of the top sections 51 when the box is assembled. Tabs 58 on the sides 52 are disposed to fit into the openings 59 in the flaps 56 so that the box, when .set up, assumes the position shown in Figure 8.

, In the form shown in Figure 9, the means for connecting the flaps 64 of the top sections 65 preferably comprise the tabs 66 each of which has laterally extending arms 61 arranged to be inserted in the slits 68 in the opposed sides 69. Each tab also has an end portion I0 arranged to overlap the adjacent side 69 so that the tabs, when the box is assembled, assume the position as shown in Figure 10.

In the blank shown in Figure 1.1, the bottom 'II has the opposed pair of extensions I2 and I3 respectively, which are arranged to be folded along the score lines I4 to constitute the sides of the box. The adjacent corners of the sides are preferably formed by the cut-away flanges or flaps I5 arranged to be folded along the diagonal score lines I6 so as to assume positions parallel to the adjacent sides of the box and reinforce the comers when the box is assembled. Either this form of comer construction or others, "such as that shown in the previous forms may be employed in making the various modifications disclosed. The sides I3 are connected to the flaps II of the top sections I0 by the hook-shaped tabs facilitate the introduction of the tabs into the slots IS, the side I3 adjacentthe slots, may have a hand engaging portion or flap 00 so as to separate the walls of the slots I9 to permit the easy insertion or removal of the tabs I9. Manifestly other forms of .the invention may be provided with similar means for opening the slots that receive the locking members. I

A box formed by a blank shown in Figure 13 has'a bottom I provided with the opposed pairs of projections I42 and I43 respectively which, whenfolded along the score lines I44, constitute the sides of the box. The projections I42 terminate in the top sections I45 which are simila y In order to 4 formed and have the flaps I46 which are provided with the tabs I4'I arranged to fit within the slots I40 in the sides I43. Additionally, the projections I42 have interlocking tongues I43 which are received in the slits I50 in the side I43. Each of the top sections I45 has an intermediate flap I5I andend flaps I52 arranged to overlap and assume the position shown in Figure 14 when the box is assembled. It will be seen that by reason of the interlocking connection of the sides I42 and I43 by thetongues I43 engaging with the slits I50, that the top sections I45 may assume an open position when the sides are assembled.

In the form of the invention shown in Figure the bottom I54 as well as the opposed pair of sides I55 and I56 and the top sections I5'I may be substantially the same as the corresponding parts just previously described. The sides I56, howcorresponging parts previously described, and

has the side flaps 200 arranged to be bent downwardly along the score lines 20I s'othat these flaps will overlap the sides, and the tabs 202 be received in a complementary slot in one oi the sides in the manner as previously set forth. In order to reinforce the handle 203, each of the top sections may have cut-out portions 204 of suflicient length that when these portions are bent back upon the top section, they will extend across the base of the handle 203 which, in the meantime, has been bent upwardly so as to rein-.

force the handle at its point of connection with I the top. A slot 205 is formed in the top section so as to receive the free end of the cut-out portion 204 for maintaining the latter across the base of the handle in the manner as shown in Figure-18. As shown in Figure 13, the base of each of the handles I53 is reinforced by the cutout portions 204 which are arranged to be bent so as to fit into the slits 205 in substantially the same manner as shown in Figure 18.

Figures 19 and 20 show another modification of reinforcing means and differs from the form.

just described, in that the cut-out portions 206 have their free ends terminating in tabs 201,

which are provided with curved hooked arms 200, each arranged to extend within the slit 209 in the top section 2 I0.

In Figures 21 and 22, a curved cut-out portion 2I2 is provided which is arranged to be bent along the score line 2I3 so as to extend across the base 01' the handle 2. The cut-out portion 2I2 has a locking head 2I5 which fits within a slot H0 in the top section 2".

Figure 23 shows a modification somewhat similar to the form disclosed in Figure 13, but escentially distinguishes therefrom, in that the tabs 220 on the projections 22I of the base 222,

'terminate in laterally disposed hooks ,223 arfrom Figure 23, in that the opposed pair of projections 226 have substantially arrow-shaped locking tabs 221 extending lengthwise therefrom,

so that when the box is assembled, the reduced.

portions 228 of the tabs are arranged to extend through a slot 229 and be bent so that the head of the-tab may fit within a slit 230 formed in the other pair of projections 23l in the manner as shown in Figure 26. In order to insure a firm interlocking engagement of the tabs 221 with the slits 230, the latter have their ends 232 bent away from the slot 229. Otherwise this form of box is substantially the same in construction as that shown in Figure 23.

It will be manifest from the number of modifications, illustrating the invention, that various forms of locking means may be employed for connecting the parts together and that the handle portion may assume different shapes and be detachably connected to the sides of the box by various other means than those shown without departing from the spirit of the invention and the scope of the appended claims.

Moreover, the corner sections between the sides may be either triangular, as shown in certain of the forms, or may be partly or wholly cutaway.
